Definitions
- the present invention relates to a liquid-absorbing core used in an absorption-type chemical agent vaporization apparatus.
- Absorption-type chemical agent vaporization apparatuses that absorb chemical solutions such as aromatic substances, deodorants, insect repellents, and pesticides by means of liquid-absorbing cores, members for absorption, and diffuse them in the environment have conventionally been provided.
- the liquid-absorbing cores are synthetic fibers such as polyester, polypropylene and acetate blended with heat-fusible fibers and formed into pillars, that lead chemical solutions contained in the containers to the mouths of the containers through capillary action.
- the chemical solutions lead to the mouths of containers develop into fumes that diffuse to provide the environment with the effects of chemical agents.
- the volume tends to increase recently and absorption-type chemical agent vaporization apparatuses with containers that are larger and taller than before are under development.
- a conventional liquid-absorbing core is used for this tall container, the chemical solution can be absorbed up and diffused to the environment without trouble during initial stage of use when the container is filled with the chemical solution up to the top (high position).
- the force of absorption is not enough to lead the chemical solution up to the mouth of the container. Therefore, diffusion stops although the chemical solution is left, resulting in a problem that performance of a large chemical solution diffusion apparatus cannot be fully exerted.
- the present invention has been done in view of such a problem, and aims at providing a liquid-absorbing core that leads the chemical solution to the last drop up to the mouth of the container to diffuse it even when a tall large container is used.
- the present invention provides a liquid-absorbing core comprising hydrophilic fiber and/or water-absorbing fiber.
- the hydrophilic fiber used for the present invention is a fiber having affinity to water such as rayon, cotton and pulp. Rayon is preferably used because of particularly high affinity to water and good processability that enables easy formation of the liquid-absorbing core in the predetermined shape helped by its length.
- water-absorbing synthetic fibers such as polyvinylalcohol and sodium polyacrylate, and other synthetic fibers treated with polyvinylalcohol or sodium polyacrylate by adhesion or coating can be mentioned as the water-absorbing fibers used for the present invention.
- “Lanseal” from Toyobo
- the liquid-absorbing core of the present invention may have voidage of hydrophilic fiber and/or water-absorbing fiber of 10% to 80%. Voidage of over 80% leaves too large openings to absorb the chemical solutions high enough, and that of less than 10% reduces the amount of the chemical solution absorbed up and non-volatile ingredients (such as surfactants and dyes) fill the openings so that upward absorption of the chemical solutions may stop.
- non-volatile ingredients such as surfactants and dyes
- the liquid-absorbing core of the present invention can be obtained by simply bundling hydrophilic fiber and/or water-absorbing fiber, or by weaving them into threads or strings. Also, the bundles of hydrophilic fiber and/or water-absorbing fiber can be rolled with films or tapes of polyethylene, polypropylene or cellophane to form pillars.
- liquid-absorbing core of the present invention is formed by blending hydrophilic fiber and/or water-absorbing fiber with heat-fusible fiber and heat-fusing the same.
- Polyethylene, polypropylene, low melting point polyester, and core-sheath fiber of PET/PE can be mentioned as the heat-fusible fibers used for the present invention.
- low melting point polyester with a wide range of heat fusion temperature is preferably used in view of heat-fusibility and productivity.
- Conventionally known methods can be used for blending hydrophilic fiber and/or water-absorbing fiber with heat-fusible fiber.
- the blended fibers can be molded into desired shapes by conventionally known methods.
- the ratio of blending of hydrophilic fiber and/or water-absorbing fiber with heat-fusible fiber can be selected within the ranges of 95% to 15% of the hydrophilic fiber and/or the water-absorbing fiber and 5% to 85% of the heat-fusible fiber. Less than 5% of the heat-fusible fiber causes difficulty in formation of the liquid-absorbing core, and over 85% of it reduces the effect of upward absorption of the liquid.
- the present invention provides a liquid-absorbing core molded into pillars by gluing hydrophilic fiber and/or water-absorbing fiber with an adhesive.
- Polyurethane resin and epoxy resin can be mentioned as the adhesive.
- Another synthetic fiber can be blended in the present invention for the purpose of prevention of fuzz and improvement of moldability.
- Moldability means reduction of frictional resistance with the molding machine for improvement of smoothness of extrusion in extrusion molding of the liquid-absorbing core of the present invention.
- Polyester and nylon can be mentioned as the synthetic fibers used in the present invention.
- the ratio of the synthetic fiber to be blended is up to 80% of the whole composition of the core. The ratio of over 80% prevents exertion of the effect of high absorption of the liquid even though smoothness of extrusion may be obtained.
- the liquid-absorbing core of the present invention can be used in conventionally known absorption-type chemical agent diffusion apparatuses.
- the chemical solution is placed in a container equipped with an opening mouth, and a liquid-absorbing core of the present invention is positioned to reach from the mouth to the bottom of the container that leads the chemical solution in the container to the mouth through a capillary action.
- the chemical solution led to the mouth develops into volatile that volatilizes to provide the environment with effects of chemical agent.
- liquid-absorbing core of the present invention in such an absorption-type chemical agent diffusion apparatus enables the apparatus to lead the chemical solution to the above-mentioned mouth even when the amount of the chemical solution is reduced and the solution is left only at the bottom of a tall container that conventionally does not allow absorption of liquid to the top.
- FIG. 1 is a schematic view of the absorption test method.
- Polyester 3 kg as a synthetic fiber, rayon 4 kg as water absorbing fiber, and low melting point polyester 3 kg were carded with a carding machine to obtain tops. Eight tops obtained were drawn several times with a leveler to obtain slivers. The sliver thus obtained was sent through a cylindrical heater heated at 230 to 240° C. and then through a cooling nozzle to obtain a 4 ⁇ thick liquid-absorbing core. The voidage of this liquid-absorbing core was 60%. The liquid-absorbing core of this example thus obtained and cut to the length of 20 cm absorbed a solution of an aromatic substance up to the top when its lower end was dipped in it.
- Rayon fiber was weaved into strings to prepare a liquid-absorbing core.
- the voidage of this liquid-absorbing core was 70%.
- the liquid-absorbing core of this example thus obtained and cut to the length of 20 cm absorbed a solution of an aromatic substance up to the top when its lower end was dipped in it.
- “Lanseal”, trade name, (a product of Toyobo) was carded with a carding machine to obtain tops. Four tops thus obtained were drawn several times with a leveler to obtain slivers. The slivers obtained were wound with polypropylene tape to prepare a pillar-shaped liquid-absorbing core. The voidage of the liquid-absorbing core was 30%.
- the liquid-absorbing core of this example thus obtained and cut to length of 20 cm absorbed an aqueous solution of an aromatic substance up to the top, when its lower end was dipped in it.
- tops were drawn several times with a leveler to obtain slivers.
- the slivers obtained were sent through a blow-molding machine for polyethylene to inject polyethylene around the wall of the slivers. This was sent through a water bath for cooling to obtain a pillar-shaped liquid-absorbing core.
- the voidage of the liquid-absorbing core was 80%.
- the liquid-absorbing core of this example thus obtained and cut to length of 20 cm absorbed an aqueous solution of an aromatic substance up to the top, when its lower end was dipped in it.
- Pulp 5 kg and low melting point polyester 5 kg were thoroughly mixed and flattened to form a 10 cm thick sheet, that was sent through a hot roller heated at 230° C. to 240° C. to obtain a 1 cm thick sheet.
- the voidage of the sheet thus obtained was 30%.
- This sheet was cut into a 1 cm wide by 20 cm long piece to obtain a square pillar-shaped liquid-absorbing core of the present invention.
- the liquid-absorbing core of this example thus obtained absorbed an aqueous solution of an aromatic substance up to the top, when its lower end was dipped in it.
- Examples 1-1 through 1-7 and Comparative examples 1 and 2 are shown in Table 1 below.
- liquid-absorbing cores were obtained in the same manufacturing steps as in Example 1 described above, and with examples of blending ratios (in % by weight) shown in Table 1 below. Voidages in these Examples 1-1 through 1-7 and Comparative examples 1 and 2 were all 60%.
- Examples 1-1 through 1-5 comprising rayon or cotton that are hydrophilic fibers and Examples 1-6 and 1-7 comprising PVA-glued PET or polyvinylalcohol that are water-absorbing fibers were given “ ⁇ ” for both “moldability” and “absorption”.
- Examples 1-8 and 1-9 and comparative Example 3 are shown in Table 2 below.
- liquid-absorbing cores were obtained in the same manufacturing steps as in Example 1 described above, and with examples of blending ratios (in % by weight) shown in Table 1 below. Voidage was calculated by the same equation shown above and “absorption” was similarly evaluated using a similar test apparatus as in Table 1 shown above.
- Examples 1-8 and 1-9 comprising hydrophilic fiber, rayon, with voidage of 10% and 80% respectively were given “ ⁇ ” for “absorption”.
- Comparative examples 1 and 2 not comprising hydrophilic fiber or water-absorbing fiber were given “x” for “absorption” while they were given “ ⁇ ” for “moldability”.
- the liquid-absorbing core of the present invention exerts the effect of absorbing liquid high above. Therefore, when an absorption-type chemical solution diffusion apparatus using a container that is larger and taller than conventional ones is used, sufficient absorption force can be secured to enable leading chemical solutions to the mouth of the container, even when only a small amount of the chemical solution is left as period of use passed, and the chemical solution is left only at the bottom of the container. Therefore, the chemical solution can be lead to the last drop up to the mouth of the container to diffuse.
